CCQM-K41.2017
MEASURAND Amount-of-substance fraction of hydrogen sulfide in nitrogen
NOMINAL VALUE 10 µmol/mol
Degrees of equivalence represented by Di = (xI - xR) and its expanded uncertainty Ui at a 95 % level of confidence, both expressed in µmol/mol.
The gravimetric determination carried out by KRISS of the amount of substance fractions were adopted as key comparison reference values xR,i and associated standard uncertainty uR,i for each institute Labi.
Di = (xi - xR) and its expanded uncertainty Ui at a 95 % level of confidence where Ui = 2 ui.
